symbol can be placed above, be-
low or to the lef t or right of the Tire
Identification Number.
2. Two-digit code: Manufacturer's identification mark. 3. Two-digit code: Tire size.
4. Three-digit code: Tire type code
(Optional).
5. Four numbers represent the week and year the tire was built.
For example, the numbers 3103
means the 31st week of 2003. If
these numbers are missing then
look on the other sidewall of the
tire.
O3Tire ply composition and material
The number of layers or plies of
rubber-coated fabric in the tire. Tire
manufacturers also must indicate
the materials in the tire, which in-
clude steel, nylon, polyester and oth-
ers.
O4Maximum permissible inflation
pressure
This number is the greatest amount
of air pressure that should be put in
the tire. Do not exceed the maximum
permissible inflation pressure.
O5Maximum load rating
This number indicates the maxi-
mum load in kilograms and pounds
that can be carried by the tire. When
replacing the tires on the vehicle, al-
ways use a tire that has the same
load rating as the factory installed
tire.

Other Tire-related Terminology
In addition to the many terms that
are defined throughout this section,
Intended Outboard Sidewall is (1) the
sidewall that contains a whitewall,
bears white lettering or bears
manufacturer, brand, and/or model
name molding that is higher or
deeper than the same molding on
the other sidewall of the tire, or (2)
the outward facing sidewall of an
asymmetrical tire that has a particu- lar side that must always face out-
ward when mounted on a vehicle.
TYPES OF TIRES

Summer tires
NISSAN specifies summer tires on some
models to provide superior performance
on dry roads. Summer tire performance is
substantially reduced in snow and ice.
Summer tires do not have the tire traction
rating “M&S” on the tire sidewall.
If you plan to operate your vehicle in snowy
or icy conditions, NISSAN recommends the
use of SNOW tires or ALL SEASON tires on all
four wheels.
Snow tires
If snow tires are needed, it is necessary to
select tires equivalent in size and load rat-
ing to the original equipment tires. If you do
not, it can adversely affect the safety and
handling of your vehicle.
Generally, snow tires have lower speed rat-
ings than factory equipped tires and may
not match the potential maximum vehicle
speed. Never exceed the maximum speed
rating of the tire.
If you install snow tires, they must be the
same size, brand, construction and tread
pattern on all four wheels.For additional traction on icy roads, stud-
ded tires may be used. However, some U.S.
states and Canadian provinces prohibit
their use. Check local, state and provincial
laws before installing studded tires. Skid
and traction capabilities of studded snow
tires on wet or dry surfaces may be poorer
than that of non-studded snow tires.
TIRE CHAINS
Use of tire chains may be prohibited ac-
cording to location. Check the local laws
before installing tire chains. When installing
tire chains, make sure they are the proper
size for the tires on your vehicle and are
installed according to the chain manufac-
turer's suggestions.
Use only SAE class “S”
chains. Class “S” chains are used on ve-
hicles with restricted tire to vehicle clear-
ance. Vehicles that can use Class “S” chains
are designed to meet the minimum clear-
ances between the tire and the closest ve-
hicle suspension or body component re-
quired to accommodate the use of a
winter traction device (tire chains or
cables). The minimum clearances are de-
termined using the factory equipped tire
size. Other types may damage your vehicle.
Use chain tensioners when recommended
by the tire chain manufacturer to ensure a
tight fit. Loose end links of the tire chain must be secured or removed to prevent
the possibility of whipping action damage
to the fenders or underbody. If possible,
avoid fully loading your vehicle when using
tire chains. In addition, drive at a reduced
speed. Otherwise, your vehicle may be
damaged and/or vehicle handling and
performance may be adversely affected.
Tire chains must be installed only on the
rear wheels and not on the front wheels.
Do not use tire chains on dry roads. Driving
with chains in such conditions can cause
damage to the various mechanisms of the
vehicle due to some overstress.
Use only the 2WD range when driving on
clear paved roads.
Do-it-yourself8-37

Engine coolant*:Replace coolant at the
specified interval. When adding or replacing
coolant, be sure to use only Genuine NISSAN
Long Life Antifreeze/Coolant (blue) or
equivalent with the proper mixture. (For ad-
ditional information on the proper mixture
for your area, refer to “Engine cooling system”
in the “Do-it-yourself ” section of this manual.)
NOTE: Mixing any other type of coolant
or the use of non-distilled water may re-
duce the recommended service interval
of the coolant.
Engine oil and oil filter: Replace engine oil
and oil filter at the specified intervals. For
recommended oil grade and viscosity refer
to “Recommended fluids/lubricants and
capacities” in the “Technical and consumer
information” section of this manual.
Evaporative emissions control vapor
lines*: Check vapor lines for leaks or loose-
ness. Tighten connections or replace parts
as necessary.
Fuel lines*: Check the fuel hoses, piping
and connections for leaks, looseness, or
deterioration. Tighten connections or re-
place parts as necessary.
Spark plugs: Replace at specified intervals.
Install new plugs of the same type as origi-
nally equipped.
CHASSIS AND BODY
MAINTENANCE:
Brake lines and cables: Visually inspect for
proper installation. Check for chafing,
cracks, deterioration, and signs of leaking.
Replace any deteriorated or damaged
parts immediately.
Brake pads and rotors: Check for wear,
deterioration and fluid leaks. Replace any
deteriorated or damaged parts immedi-
ately.
Exhaust system: Visually inspect the ex-
haust pipes, muffler and hangers for leaks,
cracks, deterioration, and damage. Tighten
connections or replace parts as necessary.
Propeller shaf t(s): Check for damage,
looseness, and grease leakage.

intervals. When driving for prolonged peri-
ods in dusty conditions, replace the filter
more frequently.
Steering gear and linkage, axle and sus-
pension parts, drive shaf t boots: Check
for damage, looseness, and leakage of oil
or grease. Under severe driving conditions,
inspect more frequently. Tire rotation:
Tires should be rotated every
7,500 miles (12,000 km). When rotating tires,
check for damage and uneven wear. Re-
place if necessary.
Transmission fluid/oil, differential oil: Vi-
sually inspect for signs of leakage at speci-
fied intervals.
Off-road maintenance: Check the follow-
ing items frequently whenever you drive
off-road through deep sand, mud or water:
• Brake pads and rotors
• Brake linings and drums
• Brake lines and hoses
• Differential, transmission and transfer case oil
• Steering linkage
• Propeller shaf t(s) and front drive shaf ts
• Engine air filter
• Clutch housing drain (AWD only)
9-6Maintenance and schedules

NOTE:Maintenance items with “” should be performed more frequently according to the “Maintenance under severe driving conditions”.
(1) If operating mainly in dusty conditions, more frequent maintenance may be required.
(2) Request the dealer to inspect the fluid deterioration data using a CONSULT. If the deterioration data is more than 77000, replace the AT fluid.
(3) If using under severe conditions such as towing a trailer, using a car-top carrier, or driving on rough or muddy roads, change (not just inspect) oilat every
30,000 miles (48,000 km) or 24 months. NISSAN recommends using Genuine NISSAN Matic P automatic transmission fluid. Using automatic transmission
fluid that is not equivalent to Genuine NISSAN Matic P may damage the transmission or impact transmission durability. Damage caused by the use of fluid
other than as recommended is not covered under the NISSAN New Vehicle Limited Warranty.
(4) Af ter 60,000 miles (96,000 km) or 48 months, inspect every 15,000 miles (24,000 km) or 12 months. Replace the drive belts if found damaged.
(5) First replacement interval is 105,000 miles (168,000 km) or 84 months. Af ter first replacement, replace every 75,000 miles (120,000 km) or 60 mont hs.
(6) Use only Genuine NISSAN Long Life Antifreeze/Coolant (blue) or equivalent with proper mixture ratio of 50% antifreeze and 50% demineralized or di stilled
water. Mixing any other type of coolant or the use of non-distilled water may reduce the life expectancy of the factory fill coolant.
(7) Periodic maintenance is not required.
(8) Periodic maintenance is not required. However, if valve noise increased, inspect valve clearance.
(9) Replace spark plug when the plug gap exceeds 0.053 in (1.35 mm) even if within specified replacement mileage.
(10) For additional information on tire rotation, refer to “General maintenance” in the section.
(11) If towing a trailer, using a car-top carrier or driving on rough or muddy roads, change (not just inspect) oil at every 20,000 miles (32,000 km) or 24 months.
* Maintenance items and intervals with “*” are recommended by NISSAN for reliable vehicle operation. The owner need not perform such maintenance in
order to maintain the emission warranty or manufacturer recall liability. Other maintenance items and intervals are required.
